Application led October 15, 1906. Serial No. 339,074.

To all whom it may concern.'

Be it known that l, JAMES H. citizen of the United States, residing at Huntingdon, in the county of Carroll and State of Tennessee, have invented new and useful improvements in Sanitary Appliances, of which the following is a specification.

This combustion The latter are represented as consisting of chamber may be formed in any desirable two plates each designated by 7 and of shal- 11o way. Tt may, as will hereinafter be set low pan-like form, said plates being shown as passing onto the plates 7 and through openand consists preferably of` a plate equipped with an outlet from which a smoke stack or pipe as 20 rises, the pipe being, therefore, in communication with the combustion chamber by Way of the flue 18. When, therefore, 70 the doors 5 and 6 are shut and when the plates and 11 are in horizontal alinement a fire can be started in the combustion chamber 2, the products of combustion lpassing from said chamber 2 to the flue 18 and thence 75 to the smoke or draft pipe and then to the atmosphere. The flue 18 in addition to serving as such also in the present case serves another important function; it constitutes a combustion chamber for I have shown mounted in said flue or auxiliary combustion chamber 18 a grate as 21. This grate is adapted primarily for wood or coal as a fuel.

In case oil is employed as a fuel, of course, I will have to employ a different type of burner, the grate being considered as one type of burner. Prior to burning out the contents of the combustion chamber or vault 2, I place on this grate 21 either coal or wood or both and kindle the same. After this, or the operations may occur in different order, I kindle a fire in the combustion chamber for burning out the fecal contents thereof. The gases generated in the act of burning out the combustion chamber pass, of course, into the flue 18 and travel toward the pipe 20. They do not, however, pass the fire in said flue for this fire or the flame consumes or vitiates the gases entering said flue so that no obnoxious gases are carried out of the pipe 20 into the 100 atmosphere. rThe grate 21 acts as a screen and when fire is not kindled thereon this grate may be utilized to prevent paper and articles being drawn out into the atmosphere y by the suction developed in the pipe 20. The grate, therefore, serves as a screen when not used as a burner. By arresting the movement4 of toilet paper and like varticles from the flue the grate or screen serves to hold these papers in the flue so that their consumption is assured.

From what has been hereinbefore stated I prefer not to deposit urine in the plates 7, but utilize for such a purpose vessel or receptacle such as 22 within which is a screen as 23 115 to prevent flies and foreign substances reaching the fluid in said vessel or receptacle. This vessel has one or more hinged lids as 24 by which the fluid in question can be initially put into the vessel or receptacle. From the latter a pipe as 25 is shown as leading and as extending into and along the chamber 2 over the plates or pans 7. Between the combustion chamber 2 and the vessel or receptacle 22, the pipe 25 is equipped with a 125 hand valve as 26 which is normally closed so as to retain the contents of the vessel 22 therein. Vhen, however, this valve is opened the fluid in said receptacle or vessel can pass therefrom and into the pipe 25, the lat,` .130

ders at 8 on the side walls 3. These plates or shallow pans rest simply on the shoulders so that when occasion requires they can be easily lifted from'place.

The top of the combustion chamber is denoted in a general way by 9 and while the same may be of any desirable character it is shown as composed of two similar wide plates 10 and three narrow plates 11 which may be conveniently cast and whichI for strength are ribbed. These plates rest upon angle irons as 12. They are not positively connected to said angle irons, but simply are supported by the same and within the privy box 13 which is ordinarily made of metal and the top or seat of which is denoted by 14. This top or seat 14 generally has two rows of holes, the covers of which are designated by 15 and which when up as shown by dotted lines in Fig. 2 rest against stops or props as 16, the latter being so positioned that when the said covers are up they will stand at an outward angle whereby when an occupant frees the same they will drop by their own weight. The privy box 13 is mounted over the chamber or vault 2 and may rest on the angle irons 12 to which I have before referred and which are upon two sides and the inner end of said box. The front end of the box may be bolted as at 17 to the front 4. Under normal conditions the two plates 10'are up and they are held in such relation by the ends of the box 153 as clearly shown in Fig. 1 so that the device can be used as a closet, matter entering the chamber 2 by the way of the openings in the top 14 of the box 13 ings separating the inner plate l1 and the two outermost plates l1. I, therefore, form in effect openings in the top of the combustion chamber which are normally uncovered, but which may be closed by the lowering of the plates l() which serve as flaps or closures for said openings in said top and which When down occupy a horizontal position as shown by dotted lines in Fig. 1 in alinement with plates 11. Vhen said plates 10 are down they with the plates 11 present in effect a continuous top for the combustion chamber 2 so that the contents of said chamber can when all said plates are in horizontal alinement be burned out. During the burning out operation I prefer to remove the top 14 for the same is ordinarily constructed of wood. The box 13, however, may be made of metal so that it is unnecessary to take the same from place when the contents of the combustion chamber are being incinerated.

From the combustion chamber 2 a flue as 18 leads and this flue is preferably, though not necessarily, of the same depth as the combustion chamber and its surrounding wall may like the side and inner end walls of the combustion chamber be formed of brickwork. The top of the flue is denoted by 19 ter having within the combustion chamber 2 and directly over the pans or plates 7 perforations as 27 for the emission of such fluid. The valve 26 as stated is normally closed, it being only opened when chamber 2 are being burned out, at which time the heat in said chamber can be utilized to evaporate the urine. lt will be assumed that there is a fire in said combustion chamber and that-it is desired to dispose of the contents of the vessel 22, To do this the valve 26 is opened so that the Afluid can pass along the pipe 25 and be discharged from the same by way of the perforations 27 into or over the pans or plates 7 for evaporation. Should the fluid escape from the pans no injury can result, owing to the fact that the heat in the chamber will consume the same.

The urine receptacle 22 is preferably connected with the pipe or stack 20 by a conduit or tube as 22', by virtue of which said receptacle 22 may be properly ventilated for all odors and gases created in sail receptacle are conducted by the conduit or tube 22 into the stack 20.

The excrement catching means, consisting in the present case of the pans or plates 7, are preferably located above the bottom of the main chamber 2 in order that fuel may be placed under said pans or plates. Two of the latter are shown, but this number is not essential for in some cases only one need be employed while in other cases more may be provided.

The device hereinbefore described is sanitary and practically odorless. There is no possibility of its spreading contagion and 'flies cannot obtain access to any olf the parts;

All solid and fluid discharges can be thoroughty, quickly and readily consumed at the laces where they are deposited.

lVhat l claim is:

l. In a sanitary appliance, a combustion chamber having an excrement catching device, a privy box in cooperative relation with said combustion chamber, means for closing communication between the privy box and combustion chamber when it is desired to incinerate the contents of said combustion chamber or for opening communication between the privy box and combustion chamber to obtain deposit of matters in said chamber from said box, a second combustion chamber in communication with said iirst mentioned combustion chamber, and a urine receptacle outside of said Vfirst mentioned chamber and provided with a pipe for conveying the contents of the same into said first mentioned chamber.
